Ok, so I can come up with some hare-brained schemes; but this one takes the cake.
I was thinking about starting a 5v5 team running with nothing but Shadowstep rogues.
I know what you're thinking...just hear me out.
First, this set up would certainly have the element of surprise. Who would expect 5 sub rogues in an arena match? Many people would be too confused or laughing too hard to react after the first attack, which would go something like so...
5 Shadowstep ambushes on healer all at once.
Followed by 5 vanishes and 5 more ShS Ambs on next clothie or Leather wearer.
5 preps, 5 vanishes, 5 more ShS ambushes.
If all goes ideally, that makes the fight 5v2 seconds into the fight.
I realize this will never work in higher brackets, where Stam and Resil on arena gear would make a ShS ambush laughable. It certainly wont work if the 40sec CD on shadowstep goes live in 2.3.
These problems aside, I'm just wondering how far you guys think a team like this might get.
